' INDICATOR FOR SPRING-MOTORS.

To all whom it may concern:

Be it known that 1,.THOMAS J. MASSE, a

7 subject of the King of Great Britain, re

siding at'Edmonton, Province of Alberta, Canada, have inventejd certainnew and useful Improvements in Indicators for Spring- Motors; and I'dohereby declare that the following is a full, clear, and exact description of the invention, such 'as will enable others skilled in the-art towhich it appertains to make and use the same. I

The present invention has relationto indicators for spring motors andmore pal ticularly gramophone motors and the principal object resides inthe provision of means for indicating when the motor should be wound.

With the above and other objects in view which will, hereinafter appearas the de scription continues, the invention consists of the novelfeatures of construction, combination and formation of parts, as will behereinafter more fully described and particularly pointed out in theappended claim.

In the accompanying drawings has been shown a simple and preferred formof the invention, it being, however, understood that no limitation 'isnecessarily made to the precise structural details herein exhibited, but

the right is hereby reserved to any changes,

alterations or modifications to which recourses may be had that comewithin the scope of the claim without departing from the spirit of theinvention or sacrificing the efficiency of the same. 1 7

Referring now more particularly tothe accompanying drawings wherein likeand corresponding parts are designated by similar reference charactersthroughout the several views, v

Figure 1 is a top plan view of a grainophone illustrating the indicatingdisk.

Fig. 2 is a top plan view of the motor and driving elements. i I

Fig. 3 is a side elevation of the same; and, Fig. 4 is a detail sectionof the drive shaft. In the gramophone art trouble has been experienceddue to the spring motors running down while records are being played,resulting in the mutilation of the records and more or lessinconvenience.

With the view of obviating this defect, I have provided an attachmentwhich is adapted for connection to any of the disk type of phonographand it comprises an in- Speci fication of Letters Patent. Applicationfiled october 3, 1919.

tlons.

' In the drawings the numeral 1 designates the driving motor, which issuitably supported on'the lower surface 2 of the record board 3. Thedriving motor is of the usual spring type and has gears 4 and 5 at theopposite ends and a gear 6 attached to the crank 7 is in mesh with gear5 whereby the motor is wound.

dicator, driving motor and driving connec- Motion'for'driving thegramophone is im- I parted to the motor shaft 8, which carries the largegear 9 which engages a worm 10 on the drive shaft 11. The motor shaft 8likewise carries a pinion 12 which meshes with the cog wheel being apart of the driving mechanism ofwhich the present indicator has noplace.

An indicator plate 13 is mounted on the record board 3 and bearssuitable indicating and F, the same indicating at Fthat the motor iswound up, I; when half of the power has been expended and 0, when themotor has run down. An indicator hand 30 is pivotally mounted on a pinshaft 15 on plate 13 and at its lower end has link connection 14 with arod 16. The opposite endof rod 16 is attached to a bar 17 pivotallymounted in the bracket 18, secured by screws to the lower surface 2 ofthe record board 3. i

The lower end of bar 17 is formed with a spherical portion or knob 19which pro'ects within the groove 20 of a pulley 21. his pulley 21 iskeyed to a drive shaft 22 the restricted ends 23 of which have hearingsinthe standards 24 secured by screws25 to the lower surface of recordboard 3.

Adjacent one end, shaft 22 has a screw threaded portion 24 which carriesa gear 25, thelatter meshing with the motor gear 5, Gear 25 is heldagainst lateral movement by the pinch bracket 26 secured to the lowersurface of record board 3.

Adjacent the opposite end, the shaft 22 has a square portion 27 on whichis loosely mounted a gear 28, which latter meshes with the motor gear e.A pinch bracket 29 is secured to the lower surface of the record board 3and prevents the lateral movement of gear 28, while shaft 22 is capableof rectilinear movement in both directions.

It will thus be seen that when the motor is wound up by operating thecrank 7 the gear 5 will cause gear 25 to revolve, thereby pulley 20 willlikewise travel ing in the turning of bar 17. Rod 16 is resultan'tlyactuated, as is likewise link 14- causing the shaft with 1t, resulthand30.

Having thus fully described my 'invention,

what I claim as new and desire to secure by Letters Patent is:

The combination with a phonograph having a top plate and a motorconnected therewith, gears mounted upon the opposite ends of said motor,bearings -mounted upon the 22 to travel tothe left and I It will thusbe} seen that the informaltion relative to condition of the motor willbe obtained by glancing at the indicator cover of said ahono ia )h a inshaft slido 7 P l .ably mounted in said bearlngs, movable. gears carriedby, the pin shaft, one of said gears having threaded engagementtherewith for sliding the pin shaft in the bearings upon the rotationthereof, brackets secured to the phonograph and being forked to engageopposite sidesof the gears for preventing undesired movement thereof, abracket secured within the phonograph, a bell crank lever mounted in.said bracket, 2. grooved pulley keyed to the pin shaft in which one endof the bell cran'klever rests,an indicator secured to the phonograph,and a rod connecting the bell orankHlever-with the indicator,substantially as and for the purposes set'forth. 5 1

In witness whereof I havev hereunto set my hand. 7
